Lipman, Chicago, 111., assignor to Lipman Patents Corporation, Chicago, 111., a corporation of Delaware Application April 8, 1933, Serial No. 665,071 Renewed December 9, 1936 ,7 Claims. (01. 62-116) This invention relates in general to refrigeraunit be compact in structure, that it present a flat top upon which dishes and other articles may be temporarily set, and that the refrigerating apparatus be readily detachable from the cabinet for convenience of shipment, assembly and repair.

My present invention aims to provide all of these desirable features in a construction which will be economical to manufacture and operate, and which will be efficient and durable in use.

For the purpose of facilitating understanding of my invention I have illustrated a preferred. embodiment thereof in the accompanying drawings from which, when considered in connection with the following description, theprinciples of my invention and 'many of its inherent advantages should be readily appreciated.

Referring to the drawings:

Fig. 1 is a vertical sectional view through a refrigerationassembly embodying my invention,

Fig. 21s a rear elevation thereof,

Fig. 3 is a sectional view of the. assembly detached from the cabinet and embodying a different form of condenser,

Fig. 4 he rear elevation of the assembly shown in Fig. 3, and

Fig. 5 is a transverse sectional view on the line 5-5 of Fig. 4.

By reference to Figs. 1 and 2 of the drawings it will be observed that the cabinet, with which my invention is associated, comprises a bottom 5 supported at a convenient height upon legs 6 and carrying four: upright walls, the rear wall being designated as l, the front wall as 8 equipped with the usual door 9 through which access to the storage'chamber II is attained. The walls of the cabinet embody in their construction heat insulating material as is customary, but, in this instance, the storage chamber extends to the top of the cabinet which is left open. 'An assembly comprising a closure for this opening, a frame structure and a refrigerating apparatus carried by the frame structure is adapted to v flue sidewalls.

connected angle members l2 and I3, each bent into L-shape so as to provide a"ve rtical leg disposed at the rear of the cabinet wall I and a hori- This horizontal leg is fixedly secured to-and carries a closure ll, adapted to close the opening at the upper end of the storage chamber II. A seal between the closure and the surrounding walls of the cabinet is effected by gasket 15 interposed between the upper end of the cabinet and the top it of the closure, and a further seal-is provided by a gasket l'I interposed between the lower per- NT oFF1cs zontal leg disposed over the top of the cabinet.

imeter of the closure and a bracket l8 extending around the interior of the chamber.

The refrigerating apparatus carried by the frame structure comprises a motor condenser unit l9 supported upon a shelf or bracket 2| carried by the lower end of the frame structure, a condenser 22 carried by the frame structure near its upper end, an oil cooling coil 23 carried by the frame structure above the condenser, a receiver 24 mounted in a recess in the upper face of the closure, and an evaporator 25 suspended in the storage compartment from brackets depending from the lower face of the closure l4. Suitable piping, indicated generally by 26, connecting the compressor, the condenser, the receiver and the evaporator, aifords a. circulating system forthe refrigerantin the usual manner,'and the oil cooling coil 23 through which 011 is circulated for cool- 7 ing purposes to dissipate the excess heat units generated by the motor and compressor, is connected with the motor compressor unit by piping indicated. generally by reference character 21. The details of the refrigerating apparatus need not be here further described as they are immaterial to the present invention.

When the assembly is combined in operative relation with the. cabinet, the frame assumes the position shown in full lines in Fig. 1, in which the motor compressor unit is supported beneath the storage compartment, the evaporator is in the storage compartment, the upper end of the compartment is closed by the closure l4, and the con-. denser and oil cooling coil are supported at the back of the cabinet. When the c'abinet'is placed against a wall, as is customary, the space between the rear wall of the cabinet and the room wall provides a flue through which the air will circulate upwardly around thecondenser and oil cooling coil whereby the same are cooled. These coils are supported in the frame structure between angle members and 29 rigidly secured to the,

frame members l2 and it which also form the i In the form shown in Figs. 3 to 5 the condenser 32 is of hollow sheet metal construction extending vertically adjacent the back wall 1 of the cabinet. The metal walls are of corrugated formation as shown in Fig. 5 to afford increased condensing surface and provide vertical flues-which facilitates air circulation. The topof the condenser isconnected with the compressor by a pipe 33 and a pipe 34 connects the bottom-of the condenser with the receiver 24.-

When it is desired to disassociate the refrigerating apparatus from the cabinet for purposes of shipment, replacement or repairs, this may readily be accomplished in the following manner. First, the lower end of the frame structure is swung outwardly from the cabinet about its upward forward end as a fulcrum into the position shown in dotted lines in Fig. 1, in which position the motor compressor unit is withdrawn from beneath the cabinet, and the closure I4 is practically withdrawn from the cabinet. The whole assembly may then be removed by simply lifting the frame to free the closure from the cabinet, whereupon the assembly may be packed for shipment, or it is accessible for repairs if necessary. To reassemble the parts with the cabinet, a mere reversal of the described steps is followed. For appearances sake the top of the assembly is preferably covered and concealed from view by a removable cover 3|.

It will be apparent from the foregoing that I have provided a structure in. which the motor compressor unit is disposed beneath the cabinet, the cabinet is spaced from the floor so as to be in the most accessible position, practically the entire cubical content of the cabinet is available for food storage purposes, and the refrigerating apparatus is carried by a frame structure so that, together with this structure, it is removable as a unit from the cabinet.- The structural details illustrated and described may be varied within considerable limits without departing from the scope of this invention as defined in the following claims.

I claim:

1. The combination of a cabinet providing a storage chamber having a top opening, a removable closure for said opening, an L-shaped frame structure, one leg thereof overlying'and secured to said closure and the other leg thereof extending downwardly at the back of the cabinet, 9. motor compressor unit supported beneath said cabinet from the lower end of said frame struc ture, a condenser carried by said frame structure at the-back of the cabinet, and an evaporator suspended beneath said closure in said chamber, said assembly comprising said frame structure, closure, motor compressor unit, condenser and evaporator being removable as a unit from said cabinet upon outward swinging movement of the lower end of the frame structure about the for ward edge of said closure as a fulcrum to withdraw said motor compressor' unit from beneath the cabinet and subsequent elevation of the assembly to lift said closure from the cabinet opening ture, and a refrigerating apparatus comprising a motor compressor unit, a condenser and an evaporator, and being removable as a. unit from said cabinet, one leg of said frame structure overlying the top of the cabinet and the other leg depending adjacent the rear wall .of the cabinet and having the-condenser mounted thereon near the top of the cabinet and the motor compressor unit supported thereby beneath the cabinet, said assembly being detachable from the cabinet by swinging the lower end of the frame away from the cabinet to withdraw the motor compressor unit from beneath the cabinet and then lifting the assembly to withdraw said closure from said opening.

3. The combination of a cabinet providing a storage chamber having an opening at its upper end, an. assembly including an L-shaped frame,
